How to Rotate Elements in a List in C++ ?

Answer

To rotate elements in a list in C++ using std::list, you can use std::rotate algorithm from the header.

✐ Examples

1 Rotate Elements in a List of Integers

In this example,

We create a list named numbers with integer values using std::list.
We use std::rotate algorithm to rotate the elements by a specified distance.
Finally, we print the rotated list to standard output.

C++ Program

#include <iostream>
#include <list>
#include <algorithm>

int main() {
    std::list<int> numbers = {1, 2, 3, 4, 5};
    int distance = 2;
    std::rotate(numbers.begin(), numbers.begin() + distance, numbers.end());
    for (int num : numbers) {
        std::cout << num << " ";
    }
    return 0;
}

Output

Rotated list: 3 4 5 1 2

2 Rotate Elements in a List of Strings

In this example,

We create a list named words with string values using std::list.
We use std::rotate algorithm to rotate the elements by a specified distance.
Finally, we print the rotated list to standard output.

C++ Program

#include <iostream>
#include <list>
#include <algorithm>
#include <string>

int main() {
    std::list<std::string> words = {"apple", "banana", "cherry", "date", "elderberry"};
    int distance = 3;
    std::rotate(words.begin(), words.begin() + distance, words.end());
    for (const std::string& word : words) {
        std::cout << word << " ";
    }
    return 0;
}

Output

Rotated list: date elderberry apple banana cherry
